Definitions

  • the invention concerned here relates to a fast-closing power supply and drive adapter for the rotatable mounting of pressure cylinders to be treated in galvanic systems and its use as an overall adapter.
  • the adapter should also be easy to use and - above all - quick and easy to attach or remove.
  • the circular cylinder piston can be moved longitudinally hydraulically and / or pneumatically and / or mechanically and / or magnetically in the current intake cylinder mentioned.
  • the current intake cylinder, the circular cylinder piston and the current supply tube body consist of a metallic material that conducts the electrical current well and that the current supply tube body serves for the current-locking connection with the corresponding part of the pressure cylinder that conducts the electrical current.
  • the power supply and drive adapter mentioned preferably has a tube axis which is on the side of the printing cylinder has a stop ring for guiding the power supply tube body and for locking the piston. Furthermore, in this embodiment, the current intake cylinder on the side of the pressure cylinder contains a stop ring for guiding the power supply tube body and for locking the piston.
  • the solid axis carries a flange cover at the end opposite the pressure cylinder, which limits the stroke of the circular cylindrical piston on the said side.
  • a releasable and displaceable guide ring for locking the axle cylinder is fastened on the solid axis, which guide ring limits the stroke of the circular-cylindrical piston on the other side.
  • the current receiving cylinder at the end facing the pressure cylinder carries an inner stop ring for securing the circular cylindrical piston and that the power supply tube body at the end facing the pressure cylinder carries a sealing ring which is connected by means of an expandable bellows to a sleeve attached to the corresponding end part of the current receiving cylinder .
  • the named sealing ring has on its free side a contact ring for the purpose of securing the electrical contact to the front side of the printing cylinder, the said side is optionally provided with a corresponding current-drawing cone.
  • the power consumption cylinder is in the form of a drive device for driving the printing cylinder and / or in the form of a rotary bearing for supporting the same.
  • the overall power supply and drive adapter consists of two power supply and drive adapters according to one of the embodiments described above.
  • the pressure cylinder 15 in Figure 1 has the axis 13. This is technical Sufficiently securely attached to the power supply and drive adapter according to the invention with the counter flange 12 and the current consumption cylinder 11.
  • the axis 23 of the pressure cylinder 25 is guided through the axis sleeve 28 of the adapter and locked on the right, outside the counter flange 22, e.g. by means of a detachable bolt lock 22a.
  • the front ring 21a finally strikes the end face of the pressure cylinder 25; this side can be occupied by the cone pieces 25a which conduct well.
  • the sliding of the circular cylinder piston 24 is effected pneumatically here: through the opening 22b, the pressure fluid - preferably dry compressed air - enters and moves the cylinder piston to the left as far as it will go (of the power supply pipe section); in this position the power supply device is held by the pressure maintained; it guarantees the technically secure power supply to the printing cylinder.
  • the bellows 21b is stretched; it is fastened to both the left end of the power take-up cylinder 21 and to the front ring 21a and serves to shield the extended power supply pipe section 26 against acid droplets, dust etc.
  • the cylinder (which now carries such an adapter on both axle ends) can be placed in the bath.
  • a circular bearing 21f can be provided on each adapter.
  • the cylinder can now be rotated about its axis, possibly via a drive wheel 21g.
  • a drive without a special drive device on the adapter is also possible, namely the mounting of the adapter in / on adhesive drive rollers.
  • the electrical current required for coating is applied to the current consumption cylinder 21. From there it reaches the power supply pipe section 26 via the circular cylinder piston 24 and from there finally, if necessary via power supply cones 25a, to the surface of the printing cylinder.
  • FIG. 3 A different embodiment of the power supply and drive adapter according to the invention, which is analogous to the illustration in FIG. 2, is shown in FIG. 3.
  • the cylinder axis 33 is moved over the axis 38 of the adapter and held thereon once by means of the stop ring 39a and by means of the spring ring 39c.
  • the other components correspond to those in FIG. 2.
  • the current intake cylinder 31 on the inside on the left and the adapter axis 38 on the outside on the left each have a stop ring (39a, b) for securing the circular cylinder piston and for guiding the power supply pipe section 36.
